|Abstract: ||Femtosecond laser processes were optimized for nonlinear interactions with optical materials to develop a novel biophotonic lab-on-a-chip device that integrates laser-formed waveguides, microfluidic channels and photonic crystals (PCs). Such integration seeks the novel demonstration of dual PC functionalities: (1) efficient chromatographic separation and filtration of analytes through a porous PC embedded inside a microfluidic channel and (2) optofluidic spectroscopy through embedded waveguides that probe PC stop band shifts as varying analyte concentrations flow and separate.
The building blocks for such integration were demonstrated through the accelerated analyte flow rates measured through the embedded porous PC and the optical characterization of a PC’s stop band via integrated waveguides. Together, these laboratory results give promise for achieving simultaneous chromatographic and spectroscopic capabilities in a single PC optofluidic device. Future improvements in the laser process and possible new research directions are also offered.|
